安卓AudioRecord实现录音和播放，可以暂停和获取声音的大小，格式为amr和wav，可以对音频进行加密

最近项目要求做一个录音功能，要可以暂停的，然后对音频进行加密解密，还要根据声音大小做一个自定义的柱形图，废话不多说，下面进行录音功能实现：

项目大概长这样：

设计的思路：
由于自带的AudioRecord没有pauseRecord()方法，我把开始录音-->（暂停/继续录音）...-->停止录音叫做一次录音，点击一次暂停就会产生一个文件(.pcm)，再点击的时候对文件进行继续写入。

对类的说明：

1. AudioRecorder：封装了录音的方法：创建录音对象、开始、暂停、停止、取消，使用静态枚举类Status来记录录音的状态。
2. AudioFileUtils：文件工具类，用于文件路径的获取
3. AudioEncoder：对文件进行转码的父类，采用mvp模式，具体实现看子类的
4. AmrEncoder：继承AudioEncoder，实现父类的转码方法，amr格式。
   
5. WavEncoder：继承AudioEncoder，实现父类的转码方法，wav格式。
   
6. WaveHeader： wav文件头
7. onVoluneListener：监听录音分贝大小，用于拓展业务的处理。
8. RecordService：将录音功能集成封装在服务里面，暴露几个方法调用的接口
   
9. AESUtils：用aes对音频文件进行加解密，提高用户信息的安全性。
   

开始之前记得添加权限：

 <!-- 获取手机录音机使用权限，听写、识别、语义理解需要用到此权限 -->
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <!-- 假如我们要保存录音,还需要以下权限 -->
    <!-- 在SDCard中创建与删除文件权限 -->
    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
    <!-- SD卡权限 -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />

接下来就是关键代码：

4.AudioFileUtils（文件管理的类）

5.对音频文件进行加解密的类AESUtils：

package com.zqr.snake.mytest.record3;import android.util.Log;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.security.SecureRandom;import javax.crypto.Cipher;import javax.crypto.KeyGenerator;import javax.crypto.SecretKey;import javax.crypto.spec.IvParameterSpec;import javax.crypto.spec.SecretKeySpec;public class AESUtils {    /* 加密 */    private static byte[] encryptVoice(String seed, byte[] clearbyte)            throws Exception {        byte[] rawKey = getRawKey(seed.getBytes());        byte[] result = encrypt(rawKey, clearbyte);        return result;    }    /* 解密 */    private static byte[] decryptVoice(String seed, byte[] encrypted)            throws Exception {        byte[] rawKey = getRawKey(seed.getBytes());        byte[] result = decrypt(rawKey, encrypted);        return result;    }    private static byte[] getRawKey(byte[] seed) throws Exception {        KeyGenerator kgen = KeyGenerator.getInstance("AES");        SecureRandom sr = SecureRandom.getInstance("SHA1PRNG", "Crypto");        sr.setSeed(seed);        kgen.init(128, sr);        SecretKey skey = kgen.generateKey();        byte[] raw = skey.getEncoded();        return raw;    }    private static byte[] encrypt(byte[] raw, byte[] clear) throws Exception {        SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");        Cipher cipher = Cipher.getInstance("AES");        cipher.init(Cipher.ENCRYPT_MODE, skeySpec, new IvParameterSpec(                new byte[cipher.getBlockSize()]));        byte[] encrypted = cipher.doFinal(clear);        return encrypted;    }    private static byte[] decrypt(byte[] raw, byte[] encrypted)            throws Exception {        SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");        Cipher cipher = Cipher.getInstance("AES");        cipher.init(Cipher.DECRYPT_MODE, skeySpec, new IvParameterSpec(                new byte[cipher.getBlockSize()]));        byte[] decrypted = cipher.doFinal(encrypted);        return decrypted;    }    /**     * 加密 - AES     */    public static void Encrypt(String Path,String seed) {//        Log.d("加密 - AES", "----加密开始时间: " + new Date().getTime()/1000);        FileInputStream fis = null;        FileOutputStream fos = null;        boolean isSuccess = true;        try {            File oldFile = new File(Path);            fis = new FileInputStream(oldFile);            byte[] oldByte = new byte[(int) oldFile.length()];            fis.read(oldByte); // 读取            byte[] newByte = AESUtils.encryptVoice(seed, oldByte);            // 加密            fos = new FileOutputStream(oldFile);            fos.write(newByte);        } catch (FileNotFoundException e) {            isSuccess = false;            e.printStackTrace();        } catch (IOException e) {            isSuccess = false;            e.printStackTrace();        } catch (Exception e) {            isSuccess = false;            e.printStackTrace();        } finally {            try {                fis.close();                fos.close();            } catch (IOException e) {                e.printStackTrace();            }        }        if (isSuccess)        Log.d("加密 - AES", "加密成功");        else            Log.d("加密 - AES", "加密失败");//        Log.d("加密 - AES", "----加密结束时间: " + new Date().getTime()/1000);//        Log.i("加密 - AES", "保存成功");    }    /**     * 解密 - AES     */    public static String Decrypt(String playerPath,String seed) {//        Log.d("解密 - AES", "----解密开始时间: " + new Date().getTime());        File oldFile = new File(playerPath);//        File tempFile = new File(AudioFileUtils.getTempFileAbsolutePath(new SimpleDateFormat("yyyyMMddHHmmss").format(new Date())));        File tempFile = new File(AudioFileUtils.getTempFileAbsolutePath(oldFile.getName()));        FileInputStream fis = null;        FileOutputStream fos = null;        boolean isSuccess = true;        byte[] oldByte = new byte[(int) oldFile.length()];        try {            fis = new FileInputStream(oldFile);            fis.read(oldByte);            byte[] newByte = AESUtils.decryptVoice(seed, oldByte);            // 解密            fos = new FileOutputStream(tempFile);            fos.write(newByte);        } catch (FileNotFoundException e) {            isSuccess = false;            e.printStackTrace();        } catch (IOException e) {            isSuccess = false;            e.printStackTrace();        } catch (Exception e) {            isSuccess = false;            e.printStackTrace();        }        try {            fis.close();            fos.close();        } catch (Exception e) {            e.printStackTrace();        }//        Log.d("解密 - AES", "----解密结束时间: " + new Date().getTime());        if (isSuccess){            Log.i("解密 - AES", "解密成功");            return tempFile.getPath();        } else {            Log.i("解密 - AES", "解密失败");            return "";        }    }}  

最后就是对这些功能进行封装在服务RecordService：

package com.zqr.snake.mytest.record3;import android.app.Service;import android.content.Intent;import android.media.MediaPlayer;import android.os.Binder;import android.os.IBinder;import android.text.TextUtils;import android.util.Log;import java.io.File;public class RecordService extends Service {    private MyIBinder myIBinder;

           }        });        mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {            @Override            public void onCompletion(MediaPlayer mp) {                if (!TextUtils.isEmpty(currentPlayPath)){                File file = new File(currentPlayPath);                if (file.exists()) file.delete();                currentPlayPath = "";            }            }        });    }    private void initRecorder() {        audioRecorder = new AudioRecorder(new AudioRecorder.CallBack() {            @Override            public void recordProgress(final int progress) {               if (listener != null){                   listener.recordProgress(progress);

   }    //代理人    public class MyIBinder extends Binder implements RecordInterface{        /**         * 获取当前Service的实例         * @return         */        public RecordService getService(){            return RecordService.this;
